1. Manual Wafer Butterfly Valve Description：
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required.
2.Main Features of the Manual Wafer Butterfly Valve
a)Cast hole. Flange connection meet ANSI 125/150# DIN PN10/16 BS4504 PN10/16 in the meanwhile.

5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.
3. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q:i need exhaust valves material dimensinons of any car.
- Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.
- Q:I bought my first car recently. but it has a high idle and smoking problem, i already replaced the spark plugs. I've been reading about the exhaust gas re-circulation valve. but i cant find it. where exactly is the EGR valve located in a 1999 KIA Pride?
- all EGR valves should ( unless a very odd engine) on exhaust manifold. they will have a tube outlet returning back to inlet manifold and a control mechanism on it ( electrical connection) . these valves are known to carbon up and fail both due to soot.heat .wear etc. very possible this is the problem. a temporary fix can occasionally be found by soaking over night in cleaning fluid such as easing oil or petrol etc and washing out but this sort of fix never lasts. be aware these valves are not cheap.
- Q:It has been known that although tissue valves have lower rates of thrombotic episodescompared with mechanical valves, they are difficult to procure, and their longevity has not yet been proven. Is this true as of 2007? Thanks for answering.

- Q:My friend had heart surgery and it was pretty serious. She got a new heart. Days later they checked her and discovered that she bursted a heart valve. The doctors say it's one she can live without. That really concerns me. The valves connect directly to the heart. Please help.. Will she be ok if she doesn't get it replaced?
- You can't live without a heart valve. Your friend might have a valve regurgitation which may not be a problem depending on the valve.
- Q:primary function of a valve position?
- ...to control flow.
- Q:Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
- Mitral valve regurgitation — also called mitral regurgitation, mitral insufficiency or mitral incompetence — is a condition in which your heart's mitral valve doesn't close tightly, allowing blood to flow backward in your heart. As a result, blood can't move through your heart or to the rest of your body as efficiently, making you feel tired or out of breath. The mitral valve controls blood flow between the upper and lower chambers of the left side of the heart. The upper chamber is called the left atrium. The lower chamber is called the left ventricle.The mitral valve allows blood to flow from the left atrium into the left ventricle, but not back the other way. The heart also has a right atrium and ventricle, separated by the tricuspid valve. With each heartbeat, the atria contract and push blood into the ventricles. The flaps of the mitral and tricuspid valves open to let blood through. Then, the ventricles contract to pump the blood out of the heart. When the ventricles contract, the flaps of the mitral and tricuspid valves close. They form a tight seal that prevents blood from flowing back into the atria. Mitral valve prolapse (MVP) is a condition in which the heart’s mitral valve doesn’t work well. The flaps of the valve are “floppy” and may not close tightly. These flaps normally help seal or open the valve. From what i have read neither is better or worse and may require surgery to repair or replace the Mitral valve.
- Q:My third valve is always sticking, despite the fact that I oil them thoroughly every other day. It scrapes the sides of the case when I take it out/put it in, it's almost as if the valve is too big for it. Often times it will stick and I'll have to unscrew it and physically pull it out for it to be functional again.I've inspected it, and the inside looks just like the others which are fine. I've tried washing it, oiling it, and putting a trace amount of vaseline on it. What is the problem?
- Have you tried cleaning the valve casing (what the valve moves in)? If not, you can use a clean cloth that won't leave fibers in there, or a valve casing brush (couple dollars at the music store) to clean the inside. Many times dirt builds up at the bottom of the valve casing where it's supposed to and the valve eventually gets stuck in it. Also, like the poster above said, the plastic/metal guide could be getting caught. You can use slide grease to lubricate the slot in the top part of the valve (not the casing) where the guide moves. Just don't get any on the piston part of the valve. If all else fails, it is possible that the valve was not honed correctly at the factory and a professional will need to fix it.
- Q:I have a lawn tractor with a 10 hp Tecumseh and its running so rich because of the carburetor float valve not seating. So how should I fix this?
- A disfunctional float valve will cause the carburetor to flood from fuel spilling over the top of the float bowl. The float valve acts like a toilet valve and just fills the float bowl up to the top and closes until the level drops from the fuel evaporation being pulled off while running. I don't know the exact specs, but you should be able to guesstimate and adjust by bending the float tang, or just replace the float valve.
- Q:and that i need a valve job. what is a valve job, and is it expensive? i have a stock 1.6 SI motor in it, but i want to make my car better and faster, would it be cheaper to buy a new engine? some of the people who want to buy my car say that they would put a B16 vtec in it. what is that, and how much better is it than my engine?
- Basically a valve job is a valve backlash check and adjustment. There has to be a clearance measured in thousanths of an inch between the camshaft and the rocker assembly. This is generally measured with feeler guages.
- Q:i have a leak on the front of that valve cover and the oil is going down to the headers,,how can i fix the problem.?how do i install da gasket do i need any special things??thanx for tha help
